[PATCH v2] ia64: Disable optimizations using floating-point arithmetics

[PATCH v2] ia64: Disable optimizations using floating-point arithmetics

[Vladimir Serbinenko]

Options -minline-int-divide-* enable performing int division using floating
point unit.
They don't work in ski emulator and possibly on some real hardware.
We don't really need them, so just use normal division.
